in past 7 days i've tried setup asp.net 5 webapi using openidconnect.server resource owner flow. i more or less successful in generating token , accessing [authorize] protected actions. however, when try access this.user.identity.claims , it's empty. using asp.net 5, beta6 (having troubles upgrading recent beta7 , waiting it's official release) in startup.cs got following: public void configureservices(iservicecollection services) { services.addcaching(); services.addentityframework() .addsqlserver() .adddbcontext<authcontext>(options => { options.usesqlserver(configuration.get("data:defaultconnection:connectionstring")); }); services.addidentity<authuser, authrole>( options => options.user = new microsoft.aspnet.identity.useroptions { requireuniqueemail = true, usernamevalidationregex = "^[a-za-z0-9@_\\.-]+$" })

i have function in smarty checks if row called "mikaphotos" empty. if row empty, it's ok , doesnt happen anything, , if it's not empty..it takes value in $path variable. assin is: $smarty->assign("mikaphotos", gettheimages("somepath",400), true); and gettheimages function is: gettheimages($path,$width){ $dirname = $path; //the path $images = glob($dirname."*.png");//get png images directory foreach($images $image) { echo '<img src="'.$dirname.'/'.$image.'" width="'.$width.'" /><br />';//echo images in somepath } } now in file.tpl .. put:{$mikaphotos} , it's not working. think there problem in code, not know how that. please? function assign in smarty assigns( ! ) value returned gettheimages function mikaphotos variable. so, gettheimages function should return string instead of echoing. example, like: gettheimages($path,$width){ $res

for example: 1. item1 indented item, not list (1) 2. item2 3. item3 indented item, blank line before , after (2) 4. item4, continue list how produce (1) , (2)? you can add additional rows using shift+enter, , indent them using shift+tab here example doc: https://goo.gl/ifqeep

i updated mobaxterm 7.7 mobaxterm 8.1 on windows machine ssh , x11 needs. since doing that, vim cursors have stopped changing when enter different modes (i.e. insert mode) -- cursor block cursor. additionally, noticed if change default terminal cursor setting in mobaxterm, console cursor remains block cursor regardless (a possible bug?). in past, added following lines .vimrc file address cursor shapes, since updating mobaxterm 8.1, no longer works. let &t_ti.="\e[1 q" let &t_si.="\e[3 q" let &t_ei.="\e[1 q" let &t_te.="\e[0 q" i'm curious causing this. after doing research, found following line in mobaxterm 8.0 changelog: improvement: embedded terminal based on plain putty engine if recall correctly, have limited ability change cursors within putty environment. mean can no longer change vim cursors while using mobaxterm? alternatively, there .vimrc command don't know about? bug or intended? thanks!

i'm using select below. select a.bada, b.boom, ' ' '---', * ... there's bunch of joins along way , have data need but rows repeated respect bada , boom . not exact duplicates because values brought in star differ. however, not relevant case. the solution i'm applying listing interesting columns explicitly wonder of there's smooth way eliminate rows have bada , boom repeated (keeping 1 occurrence of such row). most databases support ansi standard window , ranking functions. such, can choose particular or arbitrary rows in set rows same values in columns: select t.* ( select t.bada, t.boom, row_number() on (partition bada, boom order bada) seqnum, t.*, table t) t seqnum = 1; this works first adding sequence number of each row over partition of original table. row number consecutive respect selected columns. once that's done, it's possible pick value of consecutive counter, e.g. 1. s

i have strange in elixir string.to_integer . nothing major, know if there's way chain functions pipe operator. here problem. line of code (you can try in "iex"): [5, 6, 7, 3] |> enum.reverse |> enum.map_join "", &(integer.to_string(&1)) returns string "3765" what want integer. have add little piece of code |> string.to_integer @ end previous statement , should have integer. let's try. piece of code: [5, 6, 7, 3] |> enum.reverse |> enum.map_join "", &(integer.to_string(&1)) |> string.to_integer gives me this: "3765" . not integer, string! if though: a = [5, 6, 7, 3] |> enum.reverse |> enum.map_join "", &(integer.to_string(&1)) string.to_integer(a) it returns me integer: 3765 . it's i'm doing right makes me mad because love chain these function way amazing pipe operator. thanks or lights. elixir fun! you need add parenthes

essentially opposite of create table workspace variables . i.e. table containing var1, var2, ... , assign var1, var2 base environment, or if called within function, assign these variables calling environment. for example: load patients patients = table(age,gender,height,weight,smoker,... 'rownames',lastname); patients has 5 variables, assign them workspace. e.g. age = patients.age , gender = patients.gender ... there way without manually typing everything? the example given in documentation think should you're looking for. completeness, i'll create table can verified: create table: load patients patients = table(age,gender,height,weight,smoker,... 'rownames',lastname); extract data table , assign variable a : a = patients{1:5,{'height','weight'}}; a 5x2 array of height , weight of patients 1-5, can seen from: whos a; hope helps!
